Given numbers are 438, 288, 777, 903

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(438, 288) = 21024

GCD(438, 288) = ( 438 x 288 ) / 21024

= 438 / 288

= 438

Step2:

LCM(6, 777) = 1554

GCD(6, 777) = ( 6 x 777 ) / 1554

= 6 / 777

= 6

Step3:

LCM(3, 903) = 903

GCD(3, 903) = ( 3 x 903 ) / 903

= 3 / 903

= 3

So, Greatest Common Divisor of 438, 288, 777, 903 is 3
